About
# Know your Storage Provider (SP) Issue claims to SPs that can be verified on-chain on the filecoin network ## Parties Involved ### Issuer (Trusted authority) - Clients trust credentials issued by the Issuer - Verifies info about SPs on filecoin network - Issues claims to SPs e.g. Geolocation claim, Reliability score, Compliance claims (GDPR, HIPAA) - Format of claims (claim schema) is published by Issuer on filecoin - How to incentivize Issuer? **- TBD** ### Holder (SP) - SPs receive claims about them from Issuers - SPs can prove facts about them, derived from info from claims, that can be verified on-chain by any actor - This allows SP to prove any fact about themself to clients on-chain - Example: SPs could sign up for a consortium of SPs that accept SPs with certain verified facts about them ### Verifier (Clients) - Clients looking for SPs can filter out potential SPs by requesting SPs to requesting proofs of facts about them - A sample proof request could be: - I am looking for Storage Provider with - Compliance claim issued by Issuer X - Reliability score issued by Issuer Y - Geolocation claim issued by Issuer X ## Flows 1. Identity creation for Issuer, SP, Verifier 2. Claim issuance to SP 3. Proof request on chain 3. On-chain proof verification
How it's made
This project uses the concepts of iden3, zero knowledge proofs to generate claims and has a rest API layer to issue claims to the Storage Providers. The verification takes place using on chain verification done by smart contracts. The frontend is built using Next JS & Typescript along with Chakra UI.
